Import Contacts
Third step of the CSV import flow. Inserts a contact_imports job row (status: "pending") and starts ContactImportWorkflow on Temporal, then returns immediately — the actual parsing/inserting happens asynchronously. If the workflow fails to start, the job row is patched to status: "failed" synchronously and the request itself still returns 502. Rows are matched against mapping (raw CSV header → canonical field, same keys as fields[].key from Preview; "" means “don’t import this column”). A row needs at least one identity field after mapping to be imported; a row is skipped if its email already exists in the org, or repeats an email already used earlier in the same file. Type-checking is lenient — an invalid cell (e.g. a malformed phone number) is dropped and the row still imports as a warning, not a hard failure. Beyond the 15 MB file-size cap shared by all three steps, there’s a second limit that’s easy to miss: at most 5,000 rows are imported per file. A CSV can sit well under 15 MB and still blow past it. Rows after the 5,000th aren’t a hard failure — each is skipped individually with the reason exceeds the 5,000-row limit, counted in skipped on Get import status and annotated per-row in that job’s result CSV, while the job itself still finishes as completed. Split larger files into separate import jobs.
